int exarg_get_int ( char *  arg_name)

Allows to get int value for a given command line argument.

Returns the value associated with the argument name. The returned may be 0 which means the user may not defined that argument or may defined it by using the 0 as value. To avoid confusing cases you should use exarg_is_defined to know if the user have used that argument and then call this function.

Returns
the value defined for this argument. If the argument is null or the exarg is not initialized the function will return -1.
